Video transcript

Hello everyone in this video. We're given this list of standard reduction potentials and we're being asked to identify which of the following species can be reduced by this. Y So let's go ahead and recall that if we lose electrons, they were dealing with an oxidation. This also means that this is a good reducing agent. On the other hand of regaining electrons, they were dealing with a reduction. And this means that we have a oxidizing agent. All right. And next is about our sl values or center reduction potential values. So if the value is lower then we have an oxidation. This means that we also have a stronger reduction or reduction reducing agents. And if the value goes up or is increasing then we have a reduction. It also means that we have a stronger oxidizing agent. Alright, so now that we have this sort of key here, we can go ahead and apply this to our problem. So for our Y value here, why has a standard production potential Being 0.24? And this is considered a lower potential value here. So here we have a reducing agent and this means that it can reduce any substances with a higher standard reduction potential value. So we can see here out of all the different species that they list, the ones that why can't be able to reduce is going to be. So we'll see can reduce our tungsten and Z two. So the one that are the statements here that respond that relate to our and so that we just wrote here is going to be statement C. Mhm. So statement C is going to be my final answer for this problem.
